Hi There,


Please help!

I am planning to set-up a T1 Inter-Cluster Trunk IP telephony lab.


Is it possible to make a Cisco 2821 router with 3 VWIC-2MFT-T1 as hub or simulated PSTN and Cisco 2801 w/ VWIC-1MFT-T1 as spokes or simulated T1 customers?


I have seen a this kind of configuration in CIPT-1 Course lab topology but instead of using a Cisco 2821 router as hub, CIPT-1 uses WS-6608-T1 voice services module. This configuration was used for Inter-Cluster voice communication.


Thanks,

negrevi

When the card is set up to use ISDN PRI signaling, ISDN data connection is not supported. The card is unable to terminate the ISDN 64 K or 56 K data connection. It supports only voice-call termination when using ISDN PRI signaling.


Also, the Multi-Flex Trunk, with or without the accompanying voice-enabling hardware, is unable to terminate a modem connection on the router in a traditional Network Access Server (NAS) dial scenario.

Hey negrevi


Are you wanting to build a PSTN switch?

If so, then I would assume that logically it cannot be the hub. It's like Cisco FR switch scenario - agree?
